So, I started it and was doing something but there is no obvious way to exit. I tried Q,q, Ecc, :q. I tried `man lnav` in separate terminal - but no man page is provided. `ps` shows 3 processes which would not die with SIGTERM, have to `kill -9`. But nice web site :)

I don't know how you got it but q and Q closes it, and there is a man page on my system at least.

Oof, sorry you had such a bad experience.

> but there is no obvious way to exit. I tried Q,q

It's not very responsive during initial indexing, which is something I need to improve. Pressing `q` should work to exit in general, though. Pressing CTRL-C three times in quick succession will force quit it.

It would help to know which version you tried. Things have gotten better over the years.

A man page exists, but only contains basic information. The builtin help text is much more extensive and can be viewed by running:

    lnav -H
There is also the documentation website: https://docs.lnav.org/

> `ps` shows 3 processes which would not die with SIGTERM, have to `kill -9`.

Older versions of lnav would use readline for the prompt and had to run it in a separate process because of "reasons". More recent versions have a custom prompt and don't require the extra processes.

Kinda neat but I had trouble using it. Not sure what it is doing or what it is even showing me. I'd recommend a more CUA-esque interface like turbo vision, the msedit of old, or micro if it had a menu.

If I have to read the manual, if it isn't blindingly obvious how to use, I'd rather just use journal or tail -f.

Also a nitpick but the colors are quite garish, perhaps 256 colors and muted or monochrome effects if possible. For some reason the colors on the site screenshot are less saturated than the one packaged in my distro, fedora, 0.12.4.

Can you elaborate a little more? lnav behaves like a pager with the conventional hotkeys for basic stuff. I'm not sure what else you are expecting.

I enjoy colors, so there's a lot going on by default. There are several themes builtin. You can configure the "grayscale" theme by running:

    :config /ui/theme grayscale
